have an original imac on the shelf that I can't seem to get working again.

The machine worked perfectly fine , but I decided to add more ram. I added the ram , tried to boot , the machine gave me a question mark face , so I figure the ram wasn't compatible. I take the ram out , try a reboot. Nothing , still question mark face.

And that's it , you turn it on and it gives a question mark face. Sure would be nice if instead of a question mark face it actually said what was wrong , so that , you know , it could actually be fixed.

Maybe they changed it in modern macs but not this one , where do I start?

That means it can't find anything to boot from. I'd check to see if the HDD is properly plugged in.

Yeah I was going to say an original iMac comes with 8.5 if you are talking about the Bondi, later 333mhz models (fruit colours) came with 8.6.

Check me out at Transcendental Airwaves on Youtube! Fast-food sucks!

Actually, the very first iMacs shipped with 8.1: http://lowendmac.com/1998/original-imac-rev-a/ Wasn't until a bit later when they started shipping with 8.5.

And to OP, I'd also suggest finding a boot CD.

I would have to buy one as the mac can't read burned disks , even burned audio cd's are a no go in it.

It was able to read a "cake" album so much so that it detected an audio program on the disk it wanted to install , so I at least know the drive works

If it's a 400Mhz or better model, booting from an external hard disk with OS8/9 installed on it would be the other option.

nope rev.A

Nuts. Thought that might be the case. Well, only other thing you could do aside from getting a CD would be to remove the HD (not a trivial task, I know) and clone an OS from another Mac of similar vintage. I don't know why I assume people have more than one old Mac lying around...

Have you tried resetting the pram and nvram. My rev.C imac did the same thing. It can boot os9 and osx 10.1 and 10.2. Installing the os works fine, but when you restart the computer it refuses to boot off the hard drive. nvram reset --> https://support.apple.com/en-us/HT204063

If this doesn't work try booting into open firmware and see if the computer even finds any bootable device, or any device for that matter.

Ayy LMAO

Have you tried resetting the nvram or pram? I'd do that first before playing with open firmware. hold command, option, P, R when turning on your mac and don't let off until you have heard the 2nd bong sound (one from the initial startup then the 2 from the nvram reset.) then release the keys. The computer will take slightly longer to boot to reconfigure bootable devices. If this doesn't work, then we need to see if the computer even reads the hard drive (the open firmware part)

Well, now you're in the same boat as me. It has to do with the NVRAM not setting (or finding) the specific bootable device.

Here are some commands in open firmware to find out the address of the hard drive.

*edit* I'll bring home my iMac and report anything useful.
